Notable investments include Coriant (formed from Siemens Optical Networks), Sycamore Networks, and Tellabs, which were merged to create a vertically integrated telecommunications equipment provider. Marlin Equity's portfolio focuses on infrastructure and specialized technology businesses serving enterprise and service provider markets.
Competitive Advantage
Marlin Equity orchestrated a multi-year consolidation of three major telecom equipment companies (Coriant, Sycamore, Tellabs) between 2013-2014. The firm successfully spun out Tellabs' telco and GPON business as a separate entity while maintaining Coriant as the core optical networking platform. Marlin's portfolio company Coriant was acquired by Infinera in 2018, representing a successful exit from optical infrastructure infrastructure investments.
